A: Howdy neighbor! The two selectable interval settings on the Country Vet Flying Insect Kill System II dispenser are labeled as 3,000 and 9,000. Selecting the 3,000 setting triggers an automatic spray burst every 15 minutes to provide continuous 30-day pest protection, while the 9,000 setting expands the delay to every 45 minutes to stretch the refill's lifespan up to 90 days.

A: Howdy neighbor! When the LED light is blinking on your Country Vet Flying Insect Kill System II dispenser, a slow green flash simply means the unit is powered on and working normally to count down its 15-minute spray interval. However, if the light turns orange or red, it is an alert indicating that your 4 AA batteries are running low or your 30-day aerosol fly spray can is empty and needs to be replaced. Swapping in a fresh refill and new batteries will reset the internal timer and keep your barn or stable completely fly-free!
